Ok so lets really talk K-members here Folks

Then you need to compare apples to apples. "control arm and what not" are expensive. And Mopar ones with T-bar provisions are more expensive to make that the Chevy A-arm with spring perch bucket. Two Mopar LCA should cost about the same or more than the custom K-member in regards to manuf costs.

But I get your general idea. And the cost difference is due to volume.

Next question is why do you feel the need for a custom K-member that has the T-bar arrangement. You're not going to get the header clearance gains from removing the T-bars nor better selection and cheaper springs.

The weight loss is mostly due to the rack. I see the going to the rack as the biggest gain, by far, in the tubular K's that retain T-bars. All that money for a rack.

Racks are nice, lightweight and precise. But the rack alone is not the Second Comming of Christ in terms of road feel and response.

These K frame threads are funny. You would think we are talking about Edelbrock heads or something. Obviously no one k-frame will serve everyone perfectly. Here is food for thought though. Chrysler spent a lot of money to engineer the T-bar suspension. In my opinion it was light years ahead of its time. It has been proven again and again to be a killer drag race and road race suspension. With that being said its also heavy and isnt perfect. I for one want a light weight version of it but I want my torsion bars. The factory chassis wasn't designed for the shock mount to take the entire weight of the front end. The RMS kit is nice and beefy and has proven to be one of the best out there, however it looks like it doesnt save much weight over the factory set up. I built my own K frame out of chromoly and with the rack its wy lighter than factory even with the torsion bars. A torsion bar doesnt weigh that much and if you look at the weight of a coilover there isn't much difference and the weight of the torsion bar is spread out over a few feet and is farther back than the shock mount thus moving the weight rearward in the chassis. All this talk about ackermann and lean in and out is fine and good but its not voodoo and can be engineered pretty easily. Any time you put a lot of caster into a front end they will lean heavily when turned.
